F ed Susieiand Harvey Reiiiga fi Mars a Iowa h Application June 8, 1933,";SerialNo. 674,830+ Y 1 5 -2' Claims. (01'. arr-'94) The present invention relates "to a cover or closure construction, and more inparticular to a novel locking mechanism for locking the cover or closure on a container.

Among the objects of the present invention is to provide a novel construction of detachable coverorclosure for a container which isadapted to be readily assembled, removed or replaced with a minimum amount of efiort, and which at all times formsa tight closure or seal for the con tainer. The present invention, although primarily adapted for use on containers holding perishable products, food or other material, is admirably adapted for use wherever a detachable and tight closure is desired or essentia A further object of the present invention is-to provide a novel construction of locking device for a cover or closure for a container, permitting the cover to be readily removed or replaced for inspection or removal of the contents, without inany way injuring the cover of itsmeans for'connecting it to the container.

A still further object is to provide a novel means and method of connecting a. cover or closure to a container such as a tub, barrel or the like, such means permitting ready removal and replacement of the cover or closure.

Another object of the invention is in the provision of a novel means for locking a cover or closure on a container and including a wire band or hoop adapted to encompass the container and provided with a lever connected to the ends of the wire band or hoop in such a manner as to lengthen or shorten the efiective length thereof, whereby to release or look the cover or closure in position.

Further objects are to provide a construction of maximum'simplicity, efliciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear, and as are inherently possessed thereby.

The invention further resides in the combination, construction, and arrangements of parts illustrated in the accompanying drawing, and while there is shown therein a preferred embodiment, it is to be understood that the same is. susceptible of modification and change, and comprehends other arrangements and details, without departing from the spirit of the invention. l

In the drawing: h

Fig. 1 is a view in perspective of a container provided with the novel closure construction.

'Fig. 2 is a fragmentary view in side elevation showing the position of the wire hoop and of the lever which is connected thereto, when the' lever has been released to permit removal of thecover; Fig.3is a view-similar to Fig. 2, but disclosing the position of the wire hoop and the lever in'lockedorlatched position. 7 1 i l Fig. 4= is a fragmentary view in perspective of' one of the connecting links attachedt'o the band or annular ring around the cover or closurej Fig. 5 is a fragmentary view in vertical cross section taken in a 55 of Fig; 1. a 1 I a Fig. 6 is a fragmentary view in vertical cross section taken-in a plane represented by the line plane represented by the I line 10- 66 of Fig; 1, but including meansforsealin'g to seat upon and close the upper end of the con- 25 tainer, and is provided with a depending band or I annular ring 4 adapted to encompass .or encircle,

the upper and outer edgeof the container.

The band or annular ring 4 has a'series of clips 5 suitably connected thereto as by welding or the 30 like. These clips are shown as doubledover and provided at their lower ends with an opening adapted to receive a hoop 6. This hoop is open and the ends 1 and 8 thereof are pivotally connected to a lever or arm 9. This arm or lever is provided at its outer end with a. rearwardly and outwardly bent flange or finger I0 adapted to be received in an ofi-set portion l l formed in the hoop 6. I

As disclosed in Fig. 3, the end or flange I0 is adapted to seat within this oiT-set portion and lock the hoop against the sides of the container by reason of the fact that when the leveror arm 9 is in the position shown in Fig. 3, the effective or operativelength of the hoop is reduced, whereby the hoop is clamped against .the sides of the tub and maintains or looks the cover in position. When the lever is raised or unlatched as shown in Fig. 2, the efiective or operative length of the hoop is increased, and it is released from its clamping engagement with the sides of the container. Thus the arm or lever is so arranged as to. vary the operative length of the hoop whereby "casion may require.

ment with the sides of the container anchors the cover in position, and when the arm or lever is moved in the other direction, the effective length of the hoop is increased and the cove'r'may be readily and easily. removed or replaced, as the oc- Each strip 5 is provided with a rearwardly-extending point or projection a which is suitably formed thereon, or pressed out from :thebody thereof. This point or projection is pressed or forced into and embeds itself in the sides of the container length of the hoop 6 is reduced by throwing the lever or arm into its looking or latching engage:

ment, and by reason of the connection of thqhoop I 'withthe turned over portionsof the clip 5, the points a are withdrawn from embedding engage; V ment with the sides of the container when the lever is thrown to unlocking position. 'lhe'sepoints or projections prevent the cover from being accidentally displaced or removed.

In-order that thecover and hoop which is adapted to be clamped ontothe container may fit containers-even though; they'vary slightly in their diameter,-this wirehoop is provided with off-sets or kinks I2 to permit an elongation of this wire. These kinks are particularly advantageous when the cover is employed onwooden containers which-are nbrmally water soaked before being filled orpacked and thus vary in their diameters, although it frequently happens thateven in card board, metal or other containers, there is aslight variation inlsize or' diameter-.

It' is often; desirable that containers, especially those containing foodstuffs orperishable products,.be sealed after they'have been inspected. In order, to permit such sealingso as to prevent tampering with the contents thereof,- the lever or arm isyprovided with an opening I3 to permit the insertion of a wire or seal-14' which maybe passed therethroughand around the hoop 6 as showninFig.:6. r, v H The present construction permits an elimination of the upper hoop of the barrel since the open hoop which is connected to the coveror' closure will take its place.- However, if the container is already supplied with such a hoop, the present construction does not necessitate its removal.

when the operative I From the above description and the disclosure in the drawing, it, will bereadily apparent that the invention oomprehends a novel construction of cover or closure for a container, which cover or closure is adapted to be readily assembled, removed or replaced, and when assembled, is latched or locked against accidental removal or displacement.

Having thus disclosed the invention, we claim:

1. A closure for a container or the like comprising a cover adapted to seat on the open end of said container, a band depending from said'cover,
